Research output: Contribution to journalArticlepeer-review


The E731 experiment at Fermilab has searched for direct CP violation in K0 which is parametrized by. For the first time all four of the KL,S modes were collected simultaneously, which greatly facilitated studies of systematic uncertainty. We find Re=-0.0004 0.0014(stat)±0.0006(syst). The result provides no evidence for direct CP violation.
